I ACTUATING MECHANISM.

To all whom it may concern: I

Be it known that I, HowARn M; Cox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Actuating Mechanisms, of which the following is -a specification. Q

.My invention relates to actuating mechanisms for operating oscillatingbodies.

The object of the invention isto provide simple and effective means for. oscillating the body about its pivot,;and as the invention is well adapted for washing machines,

Iihave illustrated it as embodied in a machine of that character.

I accomplish my bject by the mechanism illustrated in the accompanying drawings, in which I Figure 1 is a general side elevation of the machine. 2 is a plan:view' of the portion nearest the observer looking at side shown in Fig. 1. Fi 3 is an enlarged View details exhibited in Fig. 1. Fig. 4 is a sectional viewtaken on the line 4% of Fig. 3, and Fig. 5 is a perspective view of the reciprocating block or crosshead which is connected to. the actuating I spring.

Similar numerals refer to similar parts throughout the several views. In the form of machine selected to illus- I trate the invention, there is a stationary frame comprising horizontal side beams 1 and cross beams 2 supported upon legs 3 rigidified by braces 4. The tub 5 which constitutes the body to be, oscillated is pivot-1 ed to rockback and forth upon pivots 6 supported upon the frame. In the form shown, these are trunnions. held at one end in castings 7, secured to the sides of the tub and supported at the other endsin castings. 8, which rest uponthe horizontal sidebea-ms 1. y Y I Articulately connectedto the tub,lpreferably near the upper edgethereof, is an actu ating spring 10 which carries a casting 11 at its lower end. A pin, 12 extends out. wardly from said casting, and is held in p0 sition in any suitable manner, for example, by making a drive fit. A connecting rod 13 is articulately connected to said pin and is actuated by acrank 14 extending from a shaft 15, supported upon a bracket 16 Specification of Letters Patent. 1

connected mountedon the frame as best shown in Figs.

1 and 2. Said pin lis guided in its movement by a guide consisting, according to the present design, 21. The base is preferably formed integral with the casting 8; and the cap is bolted or otherwise rigidly held in position. The

of a base 20, and a cap guide surfaces of said guide are curved in the present Instance, although the radius of curvature may be varied as desired,evenn to infinityin which case the guide surfaces would be straight.

Sliding within the guide 20-21 is a block 2 1 shown in perspective in Fig. 5. Said block, which practically constitutes a; crosshead, is here shown to be provided with flanges 25 holdingit securely in position within the guide. Said block is apertured to receive pin 12, and the parts are held together with the assistance of the nut 26 screwing on the outer threaded end of the p n 12.

at their lower end tothe frame legs 3 and at the upper end to the tub 5. In

the preferred design the point of attachment at the upper end of the springs is upon extensions 32 formed integral with the casting7. I

In operation, when shaft 15 is rotated and the rod 13 caused to move back and forth it I causesblock 24 to slide back and forth in Auxiliary springs 30 and 31 are the guide 20-21. I When the block moves toward the right from the central position shown in Fig. 1,the actuating spring 10 tends to rock the tub toward the rod and thus stretch the spring 81. I The momentum of the tub causes it to overthrow, and icon- Isequently block 24 commences its return travel before the tub does. The returning block first partially releases and then restretches the spring 10 and finally this spring and the springs 31 causes the tub to oscillate in the I return direction. This movement is repeated atthe opposite end of the throw and continues as long as the machine is ,in operation, the tub of guide inwhichthe oscillating body oper-c ates, the essentials of my invention being pointed out in the accompanying claims. 1

oscillating back and" forth and stretching, first, the

1 Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is:

1. In combination, an oscillating body, a reciprocating sliding element, a spring connected at one end to said oscillating body and at the other end to said sliding element, 1

and means for causing said element to reciprocate. r I

2. In combmation, a stationary frame, a

body pivotally supported thereon, an ele-- merit slidingly mounted on said frame, a

spring connected to said pivoted body and to said sliding element and means for causing said element to slide back and forth.

In combination, a stationary frame, a guide mounted thereon, a block slidable upon said guide, means for reciprocating said block, a body pivotally supported on I said frame, and a spring connected at one end to said block and at the other end to said body.

4. In combination, a pivoted body, a reciprocating sliding block, a spring connected at one end to said block and at the other end to said body, a rotating eccentric,

an eccentric rod connected to said eccentric and adapted to actuate, said block backward and forward. I

5. In comb nation, a pivoted body, an

actuating spring connected thereto for oscil- I lating said body about the pivot, means for actuating said spring, a sliding element for controlling the path of movement of the free end of said spring, and means for guiding said sliding element.

6.'In combination, a pivoted body, an actuating spring connected thereto for oscillating said body about its pivot, a rod connected to said spring for actuating it, a stationary guide, and an element sliding back and forth in said guide and connected to said rod for controlling the movement thereof, said sliding element being actuated by said rod. I

7. In combination, a pivoted body, an actuating spring connected thereto, auxiliary springs also connected to said body for assisting incausing the oscillation thereof, a block connected to said actuating spring, a guide for said block, and eccentric mechanism for causing said block to reciprocate in its guide.

In W tness whereof, I have hereunto subscribed my name in the presence of two w1tnesses.
